Cold Rolling And Hot Rolling

Hot Rolling And Cold Rolling Concepts 1.Hot Rolling Hot Rolling is Continuous casting slabs or blooming slabs are used as raw materials, heated by a step-by-step reheating furnace, dephosphorized by high-pressure water, then entered into the roughing mill, and then into the finishing mill after cutting head and tail, and then precisely controlled by computer. After the final rolling, it is coiled by laminar cooling (the cooling rate is precisely controlled by the computer) and coiler to become a direct roll. The curling head and tail of straight hair are often tongue-shaped and fishtail-shaped, and the accuracy of thickness and width is relatively poor, and the crimping often has defects […]
